7. Fresh Lemon Water.
Lemons are perhaps the most cost-effective treatment fruit you could use for many illnesses and conditions. The strong acid in lemons can help to detox the lungs and lung tissue and a small amount can go a long way. In order to use lemon water for the natural treatment of asthma, you will need to combine two tablespoons of fresh lemon juice to one tablespoon of water. Drink this mixture every night before you sleep and repeat as much as possible. If you are able to handle the strong taste of this mixture then you can make a larger batch containing two parts lemon juice and one part water.
